Quotes
Narrator: Venus... Venus... the planet named after the Goddess of Love. This is... where I left her... 26 million miles away. Because I know she exists. I know she does! I know it! All the time we were there I heard her. Her and that sweet, haunting sound she makes, like the Sirens that tempted Ulysses... You may think I'm crazy back there on Earth. Crazy and still intoxicated by the atmosphere back there. But, wait a minute, I'm getting ahead of myself. Let me tell you the whole story. All of it from the beginning and see what you think. You be the judge!
